Compressor plays a key role in the long cycle,safe and stable operation of air separation unit.With the exten-sion of the compressor's operating cycle,the lubricating oil in the unit is oxidized.The granularity grade and varnish gener-ation tendency value will become higher,depositing on the bearings,shaft tiles and transmission parts,leading to higher shaft temperature and increased vibration,which in turn causes bearing damage.In the case of replacing the lubricating oil and cleaning the carbon deposits inside the turbo-compressor,the balanced charge attachment purification technology is used to treat the lubricating oil online.To analyse the treatment effect of on-line oil filters in conjunction with turbo-com-pressor bearing carbon cleaning tests.
